A histopathological study of granulosis virus diseases of the spruce budworm, Choristoneura fumiferana Clem., the larch budworm, Eucosma griseanaHbn.,and the imported cabbage worm, Pieris rapae Linn., has shown that the viruses may infect fat, hypodermal, tracheal matrix, and blood cells. The viruses multiply and develop within the cytoplasm of these cells appearing first as spheres and then as rods. Finally each rod becomesoccludedby protein to form a "granule".
